In the video below, the person looks like he is using Unity Personal 64 bit edition to stream a RICOH THETA S connected to his laptop with a USB cable. He also stitched the video together. It looks like the scene is the THETA S live streaming output in equirectangular format. Portions of the video show the live streaming output with the edges matching reasonably well, though still not perfect.https://youtu.be/edWrhCYIS5Q

I have some additional information on this in Japanese that I will be going through. However, if someone knows what he did, and can explain in English, it would be helpful.

I've installed Unity on a Windows machine for the first time. I can't figure out how to get the input to be the RICOH THETA S. People are using it as seen in the picture below.
